서버에 있는 '.dbf' 화일을 읽어들일려고 하는데 (FilePath와 FileName을 상황에 따라 변경됨)
다음 Error message

EOleException with message'[Microsodt][ODBC dBase Driver]'(unknown)' is not a valid parh. Make sure that the path name is spelled correctly and the you are connected to the server on which th file resides'.

Filepath는 o:\c\d\aaaa.dbf 화일 입니다

서버는 o:\\a\b\c\d 입니다
Filepath 에 서버 FullPath를 넣어도 마찬가지입니다.
고수님들의 도움을 바랍니다. 3일동안 삽질하고 있는중..
